Apure sample of barium hydroxide of mass 8.37 g was dissolved and diluted to the mark in a 250 ml volumetric flask. it was found that 5.18 ml of this solution was needed to reach the stoichiometric point in a titration of 21 ml of a nitric acid solution. calculate the molarity of the hno3 solution. answer in units of m. 007 (part 2 of 2) 10.0 points what mass of hno3 was in the sample that was titrated with aqueous barium hydroxide? answer in units of g.
